SUPERCONDUCTING RESONATING CAVITY WITH LASER WELDED SEAM AND METHOD OF FORMATION THEREOF

To provide a superconducting radio frequency (SRF) cell, a method of manufacturing the SRF cell, a welded seam usable with the SRF cell or another object, and a method of manufacturing the welded seam.SOLUTION: The superconducting radio frequency cell includes a body defining a hollow cavity having first and second opposite ends, an axis that extends between first and second irises, and an equator around the axis between the first and second irises. The body includes at least a first welded seam around the axis at a location on the body spaced from the equator. Each welded seam extends through the body and has opposite sides terminating proximate an interior and an exterior of the body, and each weld seam includes a first, conduction weld formed on one side of the welded seam and a second weld formed on the opposite side of the welded seam. The second weld can be a conduction weld, a keyhole weld, or a transition weld.SELECTED DRAWING: None 【課題】超伝導無線周波数（ＳＲＦ）セル、ＳＲＦセルを製造する方法、ＳＲＦセルまたは他の物体と共に使用することができる溶接継ぎ目、および溶接継ぎ目を形成する方法を提供する。【解決手段】第１および第２の対向する端部を有する中空の空洞を画定する本体、前記第１の絞りと前記第２の絞りとの間に延びる軸、および前記第１の絞りと前記第２の絞りとの間の前記軸周囲の赤道と、を含む超伝導無線周波数セル。前記本体は、前記赤道から離間した位置で前記本体上における前記軸周りに少なくとも第１の溶接継ぎ目を含む。各継ぎ目は、本体を貫通して延在し、前記本体の内側および外側の近傍で終端する両端を有し、各溶接継ぎ目は、前記継ぎ目の第１の側面に伝導溶接による第１の溶接を有し、その反対側に第２の溶接を有している。前記第２の溶接は、伝導溶接、キーホール溶接、または遷移溶接であり得る。【選択図】なし
